I do think the term has broadened to just capture the general decay of quality across services and software, which is probably fair since we often can't make evidenced claims about why it's happening in any specific instance. Here, it's probably fair to say that spam strategies continue to innovate and reduce their operational costs while Reddit (and most of their peers) drag their feet on responding to it as long as the spam satisfies the quality norms of the site (as sufficiently delayed replays do). Reddit (et al) presumably puts a fair effort into suppressing obvious noise, but much less effort into generated content that creates engagements or appears plausibly real, and that this *amounts to a decay over time as the implicitly permitted generated content itself becomes cheaper to produce and more widespread. Their self-benefiting inaction satisfies the original usage of "enshittening" even as the term has expanded in common use.
